Blowup (1966)

Synopsis: Italian director Michelangelo Antonioni's first English-language production was also his only box office hit, widely considered one of the seminal films of the 1960s. Thomas (David Hemmings) is a nihilistic, wealthy fashion photographer in mod "Swinging London." Filled with ennui, bored with his "fab" but oddly-lifeless existence of casual sex and drug use, Thomas comes alive when he wanders through a park, stops to take pictures of a couple embracing, and upon developing the images, believes that he has photographed a murder. Pursued by Jane (Vanessa Redgrave), the woman who is in the photos, Thomas pretends to give her the pictures, but in reality, he passes off a different roll of film to her. Thomas returns to the park and discovers that there is, indeed, a dead body lying in the shrubbery: the gray-haired man who was embracing Jane. Has she murdered him, or does Thomas' photo reveal a man with a gun hiding nearby? Antonioni's thriller is a puzzling, existential, adroitly-assembled masterpiece.
